ICD-10 Code G43.611 – Persistent migraine aura with cerebral infarction, intractable, with status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.611 – Persistent migraine aura with cerebral infarction, intractable, with status migrainosus
What it is
This code identifies a migraine disorder with persistent aura symptoms and a documented cerebral infarction, meaning a stroke-like brain injury has occurred in the setting of migraine. “Intractable” indicates the migraine is difficult to control, and “status migrainosus” means the attack is prolonged.
Clinical signs
Expect migraine features with aura that does not fully resolve, along with evidence of cerebral infarction on imaging or other documented evaluation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states persistent migraine aura with cerebral infarction and also identifies the migraine as intractable and in status migrainosus. The documentation should support all elements of the diagnosis, not just headache alone. If any part is missing, check documentation before coding.
Do not use for
Do not use this code for uncomplicated migraine, transient aura, or migraine without documented cerebral infarction. Do not assign it when the chart only suggests stroke symptoms but does not confirm the migraine-related infarction.
Coding tip
Code only when the provider documents all three qualifiers: persistent aura, cerebral infarction, and intractable status migrainosus.
